When adding a class onclick, is it possible to assess all input values and then readjust the classes based on that?

Good afternoon, apologies if this more obvious than it appears to myself,

I am having a difficult time adding classes to some input zones, is there a way to add another class to an input and then from this action continue to do more, in one streamlined section of code.

This is a diluted version of the issue I am having as I can't seem to get it to work, I still very am much a novice with JavaScript and any advice would be greatly appreciated.

<script src="jquery-1.12.4.min.js"></script>
<script type="text/javascript">
function checkSubmission(){
var inputVal = document.getelementbyclassName("compulsory").value;
if (inputVal == "") {
window.location = "";
else if (inputVal != "" && document.getelementbyclassName('redborder')) {
else {
function checkFilled(){
var inputFill = document.getelementbyclassName('redborder').value;
if (inputFill != "") {
document.getelementbyclassName('redborder').style.border-color = "green";
<style type="text/css">
border-color: red;
<button onclick="checkSubmission()">Change</button>
<input class="compulsory">

Thank you very much in advanced if you are able to assist.

Here is a "cleaned up" version I doubt it will work but if you compare it to what you have you can see all the changes mentioned above.

function checkSubmission() {
    var inputVal = document.getElementsByClassName("compulsory").value;
    if (inputVal == "") {
            window.location = "";
    } else if (inputVal !== "" && document.getElementsByClassName("redborder")) {
    } else {

function checkFilled() {
    var inputFill = document.getElementsByClassName("redborder").value;
    if (inputFill !== "") {
        document.getElementsByClassName("redborder").style.border = "thin solid green";
